3. Turn on the Ignition: Turn the ignition to the “on” position without starting the engine.
4. Power on the Scanner: Turn on the OBD2 scanner. It should automatically connect to your car’s computer.
5. Follow the Prompts: Follow the scanner’s prompts to read diagnostic trouble codes (DTCs).

3.2. Reading and Interpreting Diagnostic Trouble Codes (DTCs)

How do you read and understand DTCs? DTCs are five-character codes that provide information about the specific problem your car is experiencing. Here’s a breakdown of what each character represents:

• First Character: Indicates the system (e.g., P for Powertrain, B for Body, C for Chassis, U for Network).
• Second Character: Indicates whether the code is generic (0) or manufacturer-specific (1).
• Third Character: Indicates the specific subsystem (e.g., Fuel System, Ignition System).
• Fourth and Fifth Characters: Indicate the specific fault within the subsystem.

For example, the code P0300 indicates a random or multiple cylinder misfire.

3.3. Clearing Codes Safely

When is it safe to clear DTCs? Clearing DTCs should be done with caution. It’s generally safe to clear codes after you have diagnosed and repaired the underlying issue. However, clearing codes without addressing the problem will only result in the code reappearing.

Warning: Clearing codes can also erase important diagnostic data, so it’s a good idea to record the codes before clearing them.
